Ever sport has got its hardcore fan, and cycling is no different: it has Didi Senft, a 56-year-old cycling superfan better known as "El Diablo" (yes, he wears the devil's cape everywhere he goes).

Didi is quite famous in the cycling world; he has over 100 unusual and record-breaking bicycles. Deborah of Life in the Fast Lane has more on this guy:

Didi Senft has also built a recumbent double-decker tandem, and a giant rickshaw 42 feet (12.4 meters) long, on which the passenger sits at a dizzying height of 21 feet 10 inches (6.65 meters) above the ground.

Didi made the world’s largest soccerball bicycle out of more than 100 footballs and rode it around to promote the World Cup 2006 in Germany.
